‘The Expendables 3′ Cast Wants to ‘Bring Back Our Girls’

CANNES, France — When anything and everything can become an “event” in Cannes during the film festival, it takes a special brand of over-the-topness to pull journalists away from the frenzy of screenings and interviews.

Lionsgate has thrown its hat into the ring, first with a palatial party for “The Hunger Games: Mockingjay Part 1,” and, Sunday morning, a stunt to promote its August release of “The Expendables 3″: The studio sent tanks rolling down the Croisette, carrying cast members Harrison Ford (during a brief pause from filming “Star Wars”), Sylvester Stallone, Jason Statham, Mel Gibson, and Wesley Snipes.
